The HLS seek fixture leaves the MPEG-2 encoder thread count automatic. On a single CPU, two sampled video packets have sizes 2289 and 3904 instead of the multithreaded reference's 2330 and 3860, failing FATE. Pin the video encoder to one thread and update the two affected packet sizes. Packet timestamps, positions, and seek results are unchanged. Validated fate-seek-hls with freshly generated input three times each under CPU affinity masks containing one, two, and eight CPUs. Before this change the single-CPU runs reproduce the exact reported failure; afterwards all nine runs pass with identical test output. Fixes: #24579 Assisted-by: Fairy
